An attempt at adding pubsubhubbub support to Rietveld.
|

|
http://code.google.com/p/pubsubhubbub
|
||
|
http://code.google.com/p/rietveld/issues/detail?id=155
|
||
|
|
||
|
The server side of the protocol is trivial:
|
||
|
1. add a &lt;link rel=&quot;hub&quot; href=&quot;hub-server&quot;&gt; tag to all
|
||
|
feeds that will be pubsubhubbubbed.
|
||
|
2. every time one of those feeds changes, tell the hub
|
||
|
with a simple POST request.
|
||
|
|
||
|
I have tested this by adding debug prints to a local hub
|
||
|
server and checking that the server got the right publish
|
||
|
requests.
|
||
|
|
||
|
I can&#39;t quite get the server to work, but I think the bug
|
||
|
is not in my code. I think that the server expects to be
|
||
|
able to grab the feed and see the feed&#39;s actual URL in
|
||
|
the link rel=&quot;self&quot;, but the default value for that drops
|
||
|
the :port from the URL, and I cannot for the life of me
|
||
|
figure out how to get the Atom generator deep inside
|
||
|
django not to do that, or even where it is doing that,
|
||
|
or even what code is running to generate the Atom feed.
|
||
|
(I thought I knew but I added some assert False statements
|
||
|
and it kept running!)
|
||
|
|
||
|
Ignoring that particular problem, I would appreciate
|
||
|
feedback on the right way to get the two values at
|
||
|
the top of feeds.py marked NOTE(rsc).

This fixes the buggy tab rendering that can be seen at
|
||
|
http://codereview.appspot.com/116075/diff/1/2
|
||
|
|
||
|
The fundamental problem was that the tab code was
|
||
|
not being told what column the text began in, so it
|
||
|
didn&#39;t know where to put the tab stops. Another problem
|
||
|
was that some of the code assumed that string byte
|
||
|
offsets were the same as column offsets, which is only
|
||
|
true if there are no tabs.
|
||
|
|
||
|
In the process of fixing this, I cleaned up the arguments
|
||
|
to Fold and ExpandTabs and renamed them Break and
|
||
|
_ExpandTabs so that I could be sure that I found all the
|
||
|
call sites. I also wanted to verify that ExpandTabs was
|
||
|
not being used from outside intra_region_diff.py.
